No cryptography will protect a group that allows a traitor to join. The fundamental problem is vetting, and you really just can't do that remotely.

Not traitor, but compromised user. Given enough targets, one of them will have their device compromised. Of course the FBI has access to things more powerful than pegasus I'm sure (Just guessing).

It can protect the identity of the members, though.
